Stabalises the debugger so VS should crash less often. 

Locals window now works! (For primitive types and pointers only.) Exceptions related to unrecognised (i.e. more complex) types should be caught and display as the local variable's value instead of causing VS to crash. 
Autos window still causes instant VS crash.
Cosmos windows works.
Call Stack works (sort of...only ever displays current line)
Threads works (but there is only ever 1 thread so not very helpful)
Watch window is only capable of doing 1 watch result per break - step to next line to be able to run another - will look into why this is.
Final change for new release.
